Description
INCOLOY alloy 25-6HN is a 6% molybdenum super-austenitic stainless steel. It is an austenitic stainless steel alloy with high nickel (24%), chromium (22%), molybdenum (6%), and nitrogen (0.18%) content and is commonly known as superaustenitic stainless steel (alloys such as 254 SMO (UNS S31254) and 904L (UNS N08904) also fall under the superaustenitic designation) while 2205 (UNS S32305/ S31803) and 2507 (UNS S32750) are duplex and super duplex stainless steel, respectively. It offers an excellent combination of strength, ductility and resistance to corrosion by a variety of media at an economical price. It is readily formed and welded. The properties of the alloy are enhanced by its content of nitrogen. Its high content of nickel results in thermal stability and resistance to stress corrosion cracking. Designated as UNS N08367, alloy 25-6HN directly competes with Allegheny Ludlum alloy AL6XN®. The alloys are covered by the same ASTM, ASME, and NACE specifications. Applications are found in the air pollution control, power, chemical processing, marine, pulp and paper, and oil and gas industries. Alloy 25-6HN is a new addition to Special Metals existing line of high performance, super-austenitic stainless steels, INCOLOY alloys 25-6MO and 27-7MO.
